Application tiled November 18, 1919. Serial No. 838,870.

To all whom tmay concern Be it known that ll, CHARlEs lL. Heisman, a citizen of the United States, and resident of Schenectady, in the county oit Sche,- nectady and State of New York, have invented a certain new and useful `improvement in Disk-Forming Machines, of which improvement the following is a specification.

'My invention relates to mechanism for rolling blanks of metal into disks of desired form 1n section, and its object is to provide a machine of such character which shall be 'of substantial, and comparatively simple construction, and which shallhave the operative capacity of reducing'the metal blanks on which it acts, more nearly to the desired finished form than has heretofore been found practicable.

rlhe improvement claimed is hereinafter fullyV set forth.

lin the accompanying drawings: Figure l is a plan or top view, partly in section, of a-disk forming machine, illustrating an embodiment of my invention; Fi 2, a vertical longitudinal central section;y `ig. 3, a view, the left hand half of which is a vertical transverse section, substantially on the line 3, 3 of Fig. 1, and the right handv half, a similar section, on the line Ulilll of Fig. l; Fig. 4, a plan or top view ot the main frame or bed; Fig. 5, is a similar view of the sliding carriage; and, Fig. 6, a similar view of one ot the guide arms.

ln the practice of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, l proto time, required in operation, is imparted.

to the carriage by a correspondingl movable iuidpressure cylinder, 3, secure to one end of the carriage, the stationary piston, 3, of which cylinder, is fixed on one end of a piston rod, 3b, the opposite end of which is secured to the bed. The supply and exhaust yof motive fluid to and from the cylinder, 3, is effected by any suitable known valve mechanism, which does not, in and of itself,

Yoi the carriage, and the other ram, 4a, is

fitted to slide longitudinally in the opposite side member, and is adjusted axially by a screw, 4b.

A periphery roll, 6, the axis of which is parallel with that of the rams, 4, 4, is journalled in a sliding block, tgwhich is fitted to .be movedlongitudinally in a guide or housing, 6b, secured to the bed, 1, by thepiston 7u, of a iuid pressure cylinder, 7, secured to the bed, at the outer end of the housing, the piston being connected to the block by a piston rod 7b. The common axis of the housing and cylinder lies in the middle longitudinal plane of the bed, l,

which plane the metal blank to be rolled is located during the operation of the machine, and the housing and cylinder are longitudinally adjustable towards and from the axial plane of the rams, 4, 4', to vary the relation of the periphery roll, 6, and the side rolls, 8, 8, hereinafter described, as from time to time required.

Two side rolls, 8, 8, of conical torm,'each of which is adaptedto act u on one side of the blank, are fixed upon roll s afts, 8a, 8a, which are inwardly and oppositely inclined, at equal angles to the axis of the rams, 4, 4, and a-re journalled in bearings on swinging carriers, 9, 9, pivotally coupled to the housing, 6b, on opposite sides of its middle longitudinal plane, by pivot bolts, 9a, fitting in clamping plates, 9d, secured to the carriers by bolts, 9e, engaging T slots therein. rlhe position of the carriers may be adjusted by' said bolts and by the insertion ot shims, to accommodate changes in the sizes of the rolls or of the metal blanks. The carriers traverse in their movements about their Pivotal axes, on rollers, 9f, journalled under the top member of the bed, 1. The carriers, 9` are formed integral with, or firmly secured to, guide arms, 9", 9h, which extend from it in the direction of the cylinder, 3, and are curved towards the middle plane of the machine, at their further ends, on which rollers, 9, are journalled. The rollers, 9, bear on inclined faces, 10, shaped to the depression to be viven to the sides of the blank and presente on the sides of the two form'ers, 10,

'which are connected, adjustably, to the The side rolls, 8, are forced against the sides of the metal blank on which they act, by the pistons, 18, of fluid pressure cylin.- ders, 13, connected to the bed, 1, which pistons are Coupled, by links, 13", to pins, 13, on the carriers, 9. The cylinders, 13, can be adjusted in position on the bed, by bolts, 13d, engaging 'i' slots formed in the bed. rfhe rolls, 8, are Withdrawn from contact with the blank, after ithas .been brought to the form of the finished disk, by the pistons, 14-, of pull back cylinders, 14, fixed to the cylinders,'13, at their tops, said pistons being coupled by iinks, 14", to the pins, 13C, of the carriers, 9.

in the operation of the machine, the metal blank or cheese is fitted betiveenjthe rams, 4 and 4a, and clamped in position by the appiication of a proper degree of pressure in the cylinder, 5. Rotation is then imparted to the side rolls, 8, by their motors, 12, caus-v ing .consequent rotation of the blank, and the periphery roll, 6, is forced against the blank by the pressure exerted in the cylinder, 7. inward movement is likewise imparted to the carriers, 9, in Which the side rolls, 8, are journalled, by pressure, in the cylinders, 13, the varying extent of such movement, and the corresponding variation of the angles on Which the side rolls bear upon the blank, being governed by the traverse of the rollers, 9", along the inclined faces, 10a, of the formers, 10, as the carriage, 2, and the blank held between the rams, 4 and 4a, there on, are moved towards the periphery roll, by the pressure in the cylinder, 3. At the conclusion of the operation, the sidev rolls are withdrawn from the finished disk, by

the pistons of the pull back cylinders, 14; the pressure of the rams, 4 and 4a, on the disk is released by outward movement of the piston of the cylinder, 5; and the finished disk is Withdrawn from the machine.

l claim as my invention and desire to secure by Letters Patent:

1. In a disk forming machine, the combination of a main frame or bed; a periphery roll journalled on said bed, and movable longitudinally thereon; a carriage, fitted to slide longitudinally on the bed; a. motor for imparting movement to said carriage; clamping rams, mounted on said carriage and moving ktransversely thereto; carriers,

pivotally connected to said carriage, on opposite sides of its middle longitudinal plane.; formers, Xed on said carriage, adjacent to the end thereof further from the carriers, and having inclined faces on their outer sides; and guide arms, fixed to the carriers and bearing on the inclined faces of the formers.

2. in a disk forming machine of the type described, the combination of a carrier, a roll shaft bearing thereon; a roll shaftl` fitted to rotate in said bearing; a side roll,

fixed on said shaft; a guide arm, fixed to said carrier and projecting therefrom at an angle y to the shaft bearing; and a roller, journalled on the outer end of said guide arm.

3. in a disk forming machine, of the type in which a metal blank is subjected to the forging action of .one or more side rolls; the combination of a movable` roll supporting member; a side roll journalled on said member; means for actuating said roll; means, coupled to the supporting member, for applying power to move the roll toward and from the blank; a former corresponding to the desired final contour of the disk; and means interposed between the roll and former, and adapte-d to govern the position of the roll for the purpose of giving the desired form to the disc.
